  • Amplification for solid phase immunoassay
    Patent number: 8222046
    Abstract: The present invention is directed to immunoassays for detecting one or more target analytes in a fluid sample wherein the detection reaction occurs on a solid support and involves an amplification system. In particular, the invention is directed to making and using a test device having at least one site for detecting the presence of at least one target analyte, wherein a conjugate comprising dextran-polystreptavidin is immobilized at the test site(s) as a capture reagent for a complex containing the target analyze.
    Type: Grant
    Filed: April 29, 2009
    Date of Patent: July 17, 2012
    Assignee: Remel, Inc.
    Inventors: Zong-Li Xia, Raymond Chan, Kelly Doan
